HMS Volcano was an ammunition ship of the Royal Manticoran Navy.

In 1920 PD, Volcano was commanded by Commander Mira Badmachin and assigned to the Talbott Cluster. The ship later played a crucial role in the Battle of Monica by delivering missile pods to Captain Terekhov's improvised "squadron". (SI1)

While not directly involved in the fighting considering its role as an ammunition ship, Volcano was added to List of Honor following the battle along with all ships which had been involved.
